We report on the first record of a therizinosaur from Alaska. This record consists of a single pes track from the lower part of the Upper Cretaceous Cantwell Formation in Denali National Park, Alaska, United States. This is the northernmost occurrence for this group of dinosaurs, and the presence of this animal in Alaska offers the first support of the proposed biogeographic model of faunal exchange during the Cretaceous for these unusual theropods.
